Testing the CREE 5000 Lumen XML U2 LED HeadLight

The unit comes complete with a the LED light, rechargeable battery (with a nice nylon case), handle bar mount, and charger.

The light feels solid and well built.

So how does it perform? First off; it's bright. Really bright!!! There are three brightness setting, but honestly, the dimmest seems plenty bright. I ran the light from full charge to dead on LOW and HIGH. On LOW a 4.5 hour run time was observed. A Keithley 2110 5 1/2 digit precision digital multimeter was used to record current draw.

The battery pack puts out 8VDC, so don't connect the headlight straight to a 12VDC motorcycle or car battery without spending 60 cents for 7808 regulation.
